To all whom it 'nm e cancer n:

Be it known that I, Ol-IEsrnir E. XVARNEH, a citizen'ot' the United.Statearesiding)at Berwyn, inthepcounty ofCook-and State of illinois, have invented new and useful Improvements in Condensers,- otwhich the following is a full, clear, concise, and exact description, reference -heing 1 had i tothe accompanying drawing forming a part' of this specification.

My invention: relates to variable con-i densers,

One of the: objectsotmy invention is to provide anwiinprovedvariable friction mechanism forv controlling the niov-ement. of the rotor. plates;

A further object of; my invention is to provide an improved mounting for the st ato r plates.

Further objectsiot.my-invention will appear from the description-and claims.

In the drawings,- in which an embodiment, of my invention ,is shown:-

Fig.1 4c is,;a :section;on'theza-liner'ekei ot-- Fig-:2;

Figs- 5 liswa section on thewlinea -5-5 of Figst; and

Fig-5 6 is; a: rear view-.

Referring to 1 the drawings; in detail, thei construction shown: comprises: thel stator: platesl, the-ureter plates Q, assha'rt 3 on which the: rotor p'la tes are':mountedy a bushing hLlIl Vlllill the 'shaift. 3 oscillat-able, an adjustable friction device tor con trolling the-oscillationot-the rotor pla s, and amend trameor bracket- 5 in which the: bearing bushing -lismounted, and on which the stator- 1 plates are supported; Th esupport, such" the t'ront a panel of a ilittlit) receiving set, by mea-ns of-screws inserted through' thelopenings:in the ibosses'tj on the end ifra-rnel The 7 adj nstable friction: device xfor con-' trollingitheeaseof movement ot thevrotor plates; comprises A a Sthreeelea'l spring. washer 7 throug hwhi 'clr the-'oscillatable shaft: 3 onev tends; a-n adjusting nut 8 threaded i onto the bushings: and bearing against the leaves of the-s n'ing washer, and a collar 9 secured to the oscillatahle shaft for holding the spring 'asher against the-adjusting nut-'8. In or der to prevent: end .play of the shaft in th'e' bnshingei, the collar 9 on the shaft is positioned so that the spring washer 7 has a nice working tit between the collar 5) and theend oi the bushings. In order to hold the collar 9 in position on the shaft 3 a set screw 10 is provided. In order to hoid the spring" washer 7 against rotation with the shaft 3 the: washer is provided with an extension 11 which is secured to the end frame 5 by means of a screw 12. In order to prevent-any side play of the shaft- 25 inthe bearing bushingat the end of the bushn tudinally infonr places (Figs. 4 and 5) and the tour fingers 13thus t'0rn1edare sprung inwardly slightlyso that they exert a light spring; pressure on the shaft and prevent side play. Sideplay at the other end of the bushing. ;isprevented by providing a conical on and-extends betweenthe downwardly. ex:

tendingilugs- 18 of the endt'rame; This insulating bar 17-is secured to the lugs; 18 by means ofi screws 19. The stator" plates l areclampedtogetherandheld ona metal supporting hracketQO by means; of serous Ell. This metal supporting bracket 20, in turrn; is .SkfQlJIQCl to the insulatingvhar 17 by means of a pair otscrews extending through a metal had-Zing 23 and the insulating bar and threaded in-to tl'le' metal supporting bracket;

In 11 3. if itis desired to vary the triotional resistance to the rotation ofthe rotor plates, the nut 8 is adjustable in one directionlorthe;other-to change the spring pres sure, of thewasher'? against the collar 9.

W'hile Iihave' described but one embodiment-{of my invention it is obvious. that many modifications therein mayoccur to those adjacent-the spring washer is split longi- I skilled in the art, and I desire, therefore, that my invention be limited only by the scope of the appended claims and by the prior art.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the U. S. is:
